These new flows share main features with the Ricci flow, with typically some additional structure, but they remain more complicated than, say, the Kähler-Ricci flow. A few known cases of convergence are in [1]}, [2]}, [3]}, but otherwise very little is known as yet about their possible singularities. It is a natural first step to establish the existence of singularity models, in analogy with the case of the Ricci flow. In this paper, we carry this out for the Type IIB flow.
